Part 1 of this article will highlight a scientific study on the long-term bioavailability of the nutrients in different phosphorus fertilizers. Part 2 will provide a report on the first German production plant and present a research project in the Frankfurt Rhine-Main area. Jan Kirchhof, Glatt Ingenieurtechnik GmbH, Germany, reports on a laboratory experiment with phosphorus fertilizers and two current projects.
Production starts at first German PHOS4green plant for recycled fertilizers. Residue-free production of ready-to-use fertilizer from phosphate-containing sewage sludge ash is now possible, thanks to plant manufacturer and process expert Glatt Ingenieurtechnik, and fertilizer specialist Seraplant. The official commissioning on May 31, 2021, was attended by Prof Dr Armin Willingmann, Saxony-Anhalt’s Minister for Economics, Science and Digitalization.

Sewage sludge treatment and recycling is also an important topic for Swedish municipalities.
Under the organization of Envisys AB, a technical meeting on sewage sludge will be held in Helsingborg, Sweden. Jan Kirchhof, Senior Sales Manager Process & Plant Engineering, Glatt Ingenieurtechnik GmbH, will inform about a PHOS4green plant for the production of fertilizer from sewage sludge ash.

Jan Kirchhof, Senior Sales Manager Process & Plant Engineering, Glatt Ingenieurtechnik GmbH, will inform about a PHOS4green plant for the production of fertilizer from sewage sludge ash. At the Haldensleben site in Germany a project for an industrial-scale production plant is already being implemented. The location, the products to be manufactured and their recipes as well as the envisaged production capacities determine the economic efficiency.
Now the first plant is about to be commissioned and Glatt’s process is being used as part of a BMBF joint project in the Rhine-Main region. (article in German language)
PHOS4green – Implementation of a Plant for the Production of 60,000 t/a of Fertilizer from Sewage Sludge Ash at SERAPLANT Gmbh in Haldensleben, Germany.
In the presentation on “PHOS4green – Implementation of a plant for the production of 60,000 t/a fertilizer from sewage sludge ashes at the Haldensleben site”, Jan Kirchhof, Glatt Ingenieurtechnik GmbH and Torsten Brumme, Seraplant GmbH will present the innovative PHOS4green process, with which the essential and sought-after nutrient phosphorus can be recovered from sewage sludge ashes and used for new phosphate or compound fertilizers.
How can waste management companies in the Rhine-Main economic region join forces and make phosphorus recyclable for the nutrient cycle, as required by law from 2029? This question is being addressed by the nine players in the RePhoRM joint project. Glatt is contributing its expertise to two subprojects: the planning and construction of a container plant in Industriepark Höchst and the studies on spray granulation of purified secondary phosphorus.
Come and check out the innovative PHOS4green technology for fertilizer production out of phosphorus recyclates from sewage sludge ashes! Benefit from the information about this phosphorus recycling technology given by Jan Kirchhof, Glatt, in his lecture ‘PHOS4green Hochleistungsdünger aus Klärschlammaschen’ (PHOS4green: High-performance fertilizer from sewage sludge ashes)
From improving durability and flowability through dust reduction to a pronounced depot effect or a targeted nutrient supply via better active ingredient distribution, fluidised bed technology can deliver many benefits. The shape and size of the fertilizer granules can be determined within a defined range. The quantity of fertilizer components delivered to the soil can be adapted optimally, and significantly higher product qualities can be achieved. Solubility and protection against external influences can also be markedly improved.
